For what it's worth, MacOS has an option to synchronize the computer's time to the time standard at apple.com. Just go to Preferences:Date & Time and check the button "Set Date and Time Automatically." The apple.com time standard is linked to the bureau of standards clocks. I think that apple uses ntp behind the scenes, but you don't have to fuss with it. I used ntp in my Linux boxes, and it works fine there, too.
Get a Mac! Use Windows on it only when you have to! 73, Oliver Johns W6ODJ On Mar 10, 2009, at 1:26 AM, David Woolley (E.L) wrote: > Dick Dievendorff wrote: >> >> >> Recent versions of Windows (certainly XP and beyond) include an NTP >> client > > Although it may not matter if you only want a non-resillient time > source > accurate to a few seconds, XP only contains a (broken) > implementation of > SNTP, not NTP.
